FIELD OF THE INVENTION

TECHNICAL FIELD The present invention relates to a reusable envelope and an envelope, a method for charging the envelope, the envelope main body, and the contents used for the envelope. Background art

There are various types of packaging materials such as envelopes and other materials that can be reused, such as those that use reusable adhesive for the flaps and those that use a separate closure that covers the opening of the envelope. A configuration has been proposed. For example, the invention described in Japanese Patent Application Laid-Open No. Hei 7-219308 is known as one utilizing a separate sealing portion.

According to the invention, the opening / closing piece cut and formed in a U-shape is inserted into the opening of the packaging body, and the upper portion of the packaging body is sandwiched between the opening / closing piece and the frame piece. Prevents withdrawal. As a result, the opening of the packaging body is closed, and the packaging body can be reused. ,

However, the technology described in the publication does not mention how to provide a delivery type information section such as postage stamps and post-payment mail, or a delivery destination information section such as the name of a delivery address. In particular, if the destination information is written directly on the package itself, the package itself cannot be reused for sending.

In view of such a conventional situation, an object of the present invention is to provide an envelope that can be reused with a simple configuration, a sealing piece and an envelope body used for the same, and to provide a rational method for enclosing contents. It is in. Disclosure of the invention

A feature of the envelope according to the present invention is that the envelope body includes an envelope body and a sealing piece, and the envelope body has an opening portion opened on one side thereof, and the sealing piece is an adhesive material that can be attached to and detached from the envelope body. And that the opening is closed by being attached to the front and back of the envelope main body across the opening, and the height of the front upper end and the rear upper end at the opening of the envelope main body is made different. .

According to this configuration, since the envelope main body has a simple shape having an opening, the envelope main body is hardly deteriorated, and the sealing piece can be detached from the envelope main body by the adhesive material. After the detachment, the envelope main body is not damaged, and the envelope main body is not damaged. Are reusable. In addition, the entire configuration is extremely simple, since only a sealing piece provided with an adhesive material is attached to the envelope body.

When automatically loading the contents, for example, the upper end of the back and the lower end of the envelope body are engaged with the nail, and the front side is sucked up by suction means and lifted upward to open the opening between the upper end of the back and the upper end of the table. Can be opened. At this time, there is no inconvenience such that the two upper ends are hardly separated from each other due to the step between the upper end of the front side and the upper end of the rear side. Further, there is no inconvenience that the flap for closing the opening as in the case of the conventional envelope becomes an obstacle before the contents are charged. Furthermore, even when the contents are to be thrown in by hand, the opening can be easily opened by putting a finger on the step between the top edge and the bottom edge.

The sealing piece includes a first portion and a second portion separated through a bent portion facing the opening. Then, the width of the first portion in the direction orthogonal to the bent portion is formed to be wider than the width of the other side portion, and the first portion may be located on the slightly upper end side of the both upper ends. According to such a configuration, workability is excellent in terms of charging the contents and attaching the sealing pieces as described later. In addition, it is possible to eliminate waste of the sealing pieces. It is preferable that at least the destination information section is provided in the first portion. According to this configuration, by removing the sealing piece, the destination information section can also be removed, and reuse of the envelope is promoted.

The envelope body may be provided with an advertising section. Also, print the advertising section on the envelope body, When a transparent or translucent resin sheet is positioned on the outer surface side of the advertising section, it is possible to prevent the advertising section from being deteriorated due to abrasion or the like. For example, when the envelope main body is made of a transparent or translucent tree sheet, the advertising section may be printed from the inner surface of the envelope main body.On the other hand, the characteristic configuration of the envelope used for the envelope is as follows. It has an adhesive material that can be attached and detached, and covers the opening by being attached to the front and back of the envelope main body across the opening, so that the transmission type information section is printed. . According to this configuration, both the sealing of the envelope and the sticking of a stamp or the like can be performed simultaneously by attaching the sealing piece.

Further, a characteristic configuration of the envelope main body for use in the envelope is that an opening is opened on one side thereof, and the height of the front upper end and the rear upper end in this opening is made different.

On the other hand, a feature of the enclosing method for enclosing the contents in the envelope is that the higher end of the both upper ends is located on the lower side, and the envelope main body is supplied to the envelope supply section. According to this feature, the "higher upper end" is located on the lower side, so that the locking claw is locked to this "higher upper end" or the contents are utilized by using the "higher upper end" as a guide. An insertion piece for insertion can be inserted into the envelope. In addition, the envelope body is conveyed after the contents are charged, and the “lower upper end” is positioned on the upper side, so that the protruding portion of the bulged envelope body can be reduced, and the envelope body during transportation can be reduced. It is also possible to prevent accidental penetration due to contact with the sealing device. At the time of encapsulation, at least the upper part of the envelope main body is pulled up by the suction means, and at least the lower insertion piece is inserted through the opening, and the content is inserted along the lower insertion piece. At this time, the lower side of the envelope body may be suction-fixed to the lower side by suction means, or the locking claw may be locked to the above “higher upper end” and pulled downward. The sealing piece includes a first portion and a second portion separated through a bent portion facing the opening. Then, attach a sealing piece from the lower side of this envelope body, The width of the first portion in the direction orthogonal to the bent portion may be wider than the width of the other portion. According to the characteristic method, the wide first portion is attached to the envelope body first, and the remaining short second portion is attached to complete the sealing, so that the sealing piece can be attached more easily and smoothly. Becomes possible.

Then, it is preferable to print at least the information of the destination information section on the first portion from the upper surface of the envelope after the envelope is turned over after the sealing piece is attached. An apparatus configured to carry out such a method can be used as an apparatus for printing by enclosing the contents in an ordinary envelope with a flap.

As described above, according to the above-described features of the envelope according to the present invention, it is possible to reuse the envelope body by detaching the envelope, while the envelope body and the envelope are both extremely simple and have a simple configuration as a whole. became.
